From 339659041f87a76f8b71ad3d12cadfc5f89b4bb3 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Tue, 19 Aug 2014 23:55:52 -0700 Subject: qom: Add automatic arrayification to object_property_add() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If "[*]" is given as the last part of a QOM property name, treat that as an array property. The added property is given the first available name, replacing the * with a decimal number counting from 0. First add with name "foo[*]" will be "foo[0]". Second "foo[1]" and so on. Callers may inspect the ObjectProperty * return value to see what number the added property was given.
